In this research, we propose a noble methodology for modeling and simulation of the intensity and direction of the magnetic fields generated by coils in a limited 3-dimensional region. This method was strictly based on the Biot-Savart's law determining the magnetic fields induced by currents flowing through the coils. We also used Finite Element Method (FEM), a numerical technique for finding a solution for each subdivision of a whole domain within the regions of interest. Based on the introduction of rotational transform method for an arbitrary axis, this method possesses a strong analysis capability for the magnetic fields in the vicinity of the coil at an arbitrary position in 3-dimensional region. In addition, a linear calculation system adopted in the simulation process was able to carry on high-performance analysis for the magnetic fields generated by even multiple coils. We strongly propose that this noble method would be a powerful simulation tool for the design of a system that can generate magnetic fields within a 3-dim region of interest considering both the intensity and direction.

Remote-control technology is required in an unmanned vehicle such that it can replace humans for executing tasks in various extreme environments. In particular, a remote scene must be reconstructed using 3D meshes for enabling a user to remotely control an unmanned vehicle easily and intuitively. To this end, a large amount of multiple sensor data would be processed using various algorithms in real time. Considering the limited hardware specifications in extreme environments, it is difficult to implement 3D terrain reconstruction in high-quality and real time. This paper proposes the optimization of the architecture of a multiple-sensor-data pipeline. The improved performance resulting from the optimized architecture was analyzed through experimental comparison with a non-optimized system.

In this paper we analyze and compare the performance of support vector machine (SVM) and artificial neural network (ANN) for classification of fNIRS signals. fNIRS signals due to mental arithmetic and mental counting are acquired from the prefrontal cortex of ten healthy subjects. After preprocessing and filtering, SVM and ANN classification is performed on the same feature set - mean and slope of the changes in concentration of oxy-hemoglobin. Although no significant difference in the average classification accuracies, obtained using SVM and ANN, is observed (p = 0.2); it is noted that the standard deviation of classification accuracies using ANN is significantly higher than that of SVM. Furthermore, the computational speed of SVM is significantly higher than that of ANN. It is concluded that SVM offers stable classification accuracies and fast computation as compared to ANN.

Fall is one of the leading causes of injury and death for the elderly. Real-time fall detection is of great significance for the safety of the elderly. This paper proposes a coarse to fine fall detection algorithm based on Human characteristic matrix and Support Vector Machine (SVM). First, background subtraction and morphological processing are used to obtain more accurately human silhouette. Then, two human characteristic matrices are constructed based on Hu-moment invariant and the information of human body posture extracted from human silhouette and are used as features to train SVM classifier for fall detection. Experimental results indicate that the proposed algorithm can distinguish fall event from other movements such as squat, sitting down and back turning. Compared with other common methods, the proposed method can real-time and efficiently track the video with 18 frames per second.

This paper is concerned with the problem of decentralized H∞ proportional-plus-derivative(PD) state feed-back control of uncertain large-scale descriptor systems. The uncertainties are assumed to be polytopic type and appearing in derivative matrices as well as state and input matrices. Sufficient condition for stabilization of uncertain large-scale descriptor systems via H∞ PD state feedback is addressed in terms of Linear Matrix Inequalities(LMIs). A numerical example is given to prove the effectiveness of the proposed control method.

When 3d image registration using 2d image by hand-held scanner, the most important thing is pose estimation and object surface measure. The relationship between images is important to image registration. In this paper suggest 3d registration using Kinect and INS. The Kinect and INS are integrated on rigid body to improve the accuracy of estimate pose. It can complement the disadvantages of each sensor through the sensor fusion of INS and vision sensor position to make more precise estimates. Using purposed system can measure the three-dimensional shape of a variety of objects, and also can obtain an accurate image in a medical imaging applications which require precision application and apply in Image-guided surgery.
